Summary :
When trying to create a sales order in SAP R/3, users might encounter an error with the message 'Error in calling up function 'BAPI_APOATP_CHECK' resulting from an incorrect user type setting for the RFC User performing the ATP check. The error, detailed in APO via transaction ST22, occurs because the RFC User is not set to "DIALOG" type, which is necessary for functionalities requiring user interaction. To resolve, update the RFC user's type to "DIALOG" in APO using transaction SU01. Additionally, consider specifying a dedicated RFC destination for ATP checks post-PI2003.1 for enhanced security, and review SAP Note 727839 for authorization details.
